Facteurs associés aux perdus de vue des patients sous traitement antirétroviral dans un centre de traitement ambulatoire du VIH à Conakry,Guinée

Background

Late or inadequate therapeutic management increases the risk of mortality associated with HIV/AIDS. The aim of this study was to analyze the proportion and factors associated with loss of follow-up in HIV patients who receiving antiretroviral therapy at Conakry.

南京医科大学七年制临床医学专业人才培养效果评价

通过对毕业生及其培养或用人单位的问卷调查,本文分析了南京医科大学七年制临床医学专业人才培养的成效,以及江苏省医疗卫生事业发展对高层次医学人才的需求.结果 显示,临床实践能力和科研创新能力是医疗卫生事业发展所需要的高层次医学人才的重要能力;在三级甲等医院工作,具有硕士/博士学位、在专业技术岗位的被调查者更加看重医学生的科研创新能力;而在"1年通识教育、4年医学专业教育(含1年临床课程及见习、1年临床通科实习)、2年二级学科轮转"模式下培养的七年制临床医学专业毕业生的临床实践能力较强,但是科研创新能力不足,且学业负担偏重.因此,应当加强对七年制临床医学专业学生科研创新能力的培养和临床实践能力的通科训练.

Abstract：

An evaluation of 7-year medical education program in Nanjing Medical University was performed via questionnaire survey to the graduates and the staff of hospitals in which the graduates work,and the demand for advanced quality of medical graduates in the field of medical health care in Jiangsu Province is further analyzed. The results showed that the capacity for clinical practice and the capacity for research and innovation are the most important, which can meet the demands of health service development for high-level medical talents. The staff working in advanced hospitals, possessing master or doctor degree,or working as medical experts put more emphasis on the ability of the graduates to do innovative scientific research. Through the completed procedure of the 7-year program includes college general education for 1 year, medical education for 4 years ( containing senior clinical clerkship for 1 year and internship for 1 year) and alternation for medical and surgery subspecialties for 2 years, the graduates showed higher ability to do clinical practice, but not showed the growth of capacity for research and innovation. The most staff investigated proposed an enhancement in training for the capacity for innovative research and general clinical practice.     

Primary Ewing sarcoma: follow-up with Ga-67 scintigraphy

While avid accumulation of gallium-67 citrate and technetium-99m methylene diphosphonate (MDP) occurs initially in most cases of primary Ewing sarcoma, uptake after therapy is less well defined. Thirty patients with Ewing sarcoma who underwent Ga-67 and bone scintigraphy at diagnosis, at completion of therapy, and at relapse from 1978 to 1988 were evaluated. All 30 patients showed less primary site Ga-67 activity following therapy. Twenty-three of 28 patients who underwent corresponding bone scintigraphy showed less uptake, but residual activity was usually more intense than with Ga-67. Avid reaccumulation of Ga-67 occurred in four of five patients with primary site relapse, while patients who underwent bone scintigraphy showed less change. It was concluded that a greater decrease in Ga-67 than in Tc-99m MDP uptake often occurs in patients successfully treated for primary Ewing sarcoma. Information obtained at Ga-67 scintigraphy is most likely to be helpful if results of bone scintigraphy remain abnormal or if occult relapse is suspected.     

脾切除对结直肠癌切除术后的影响：一项多中心、嵌入式、配对队列研究

目的探讨医源性脾脏损伤脾切除对结直肠癌切除患者术后长期生存的影响。方法对1990年1月1日至1999年12月31日10年间行结直肠癌手术切除并附带脾切除患者进行病例配对回顾研究。分析患者年龄、性别、依据美国麻醉学医师协会（ASA）标准评估的身体状况、疾病分期、手术类型及预后等资料。配对病例来自同一医疗中心，性别、年龄、疾病分期及手术类型完全相同。手术附带脾切除患者为试验组，未切脾者为对照组。结果55例患者行医源性脾切除术，对照组在年龄、性别、身体状况、疾病分期及手术类型上与之匹配。随访时间（从手术开始到患者死亡或者最后一次随访1为2～205个月（中位随访时间为43个月）。Cox比例危险度模型进行Kaplan-Meier法生存分析发现两组间差异有显著性意义，不切除脾脏对患者生存有利（危险度1．8，95％可信区间为1-3．3，P=0．0399），未切脾组与切脾组5年生存率分别为70％和47％，10年生存率分别为55％和38％。结论结直肠癌患者在行结肠或直肠切除时，因医源性脾脏损伤而切除脾脏者，预后较差。     

H-FABP与GPBB早期诊断AMI的价值研究

目的:探讨H-FABP(心肌型脂肪酸结合蛋白)与GPBB(糖原磷酸化酶同工酶)在临床早期诊断急性心肌梗死(AMI)的应用指标及实用价值.方法:选取48例正常人与42例急性心肌梗死病人采用用双抗体夹心ELISA法对急性胸痛的病人在0～1h、1～3h、3～6h内快速检测H- FABP与GPBB.结果:本实验研究结果表明H-...     

SA/hIL21双功能融合蛋白的表达、纯化及生物学活性检测

目的 制备链亲和素(SA)标记的人白细胞介素21融合蛋白(SA-hIL-21),检测其生物学活性.方法 构建hIL21-SA-pET21及pET24a-SA-hIL21质粒,利用大肠杆菌BL21(DE3)表达两种双功能融合蛋白,并利用镍金属螯合层析柱(Ni-NTA)纯化,之后透析复性,Western blotting进行鉴定,最后利用MTT法检测hIL21-SA及SA-hIL21融合蛋白与抗CD3单克隆抗体(anti-CD3)共刺激人外周血淋巴细胞的增殖活性,流式细胞仪分析两种融合蛋白对生物素化的MB49肿瘤细胞的锚定修饰效率.结果 hIL21-SA及SA-hIL21重组融合蛋白在大肠杆菌中实现了高效表达,约占菌体蛋白的30%,经复性后hIL21-SA及SA-hlL21具有了双重活性,即不仅可以与抗CD3单抗共刺激淋巴细胞的增殖,而且具有了SA介导的高效结合已生物素化的MB49肿瘤细胞表面的功能(表面修饰效率95.18%,96.91%).结论 本实验成功研制了具有双重活性的hIL21-SA及SA-hlL21融合蛋白,两种融合蛋白的双功能活性无显著性差异,该项研究为SA/hIL21双功能融合蛋白应用于肿瘤疫苗以及肿瘤局部治疗奠定了基础.

Pickett FA. New guidelines for cardiac risk assessment prior to non‐cardiac surgery. Abstract: The European Society of Cardiology (ESC) has established guidelines to determine the risk for non‐cardiac procedures, such as oral procedures, when individuals have experienced severe cardiac disease, including myocardial infarction. This is the first time the ESC has developed consensus guidelines to assist practitioners in managing care for cardiac patients receiving medical or dental procedures. Factors for risk assessment are described and management for oral care is discussed.
